Too?! 00710272. it may concern:

Be-it known that I, Gannon G. MoCLuN- NY, a citizen of the United States, residing at Voodville, in the county of Bertieand "Stateof NorthCarolina,have invented certain new and useful Imprmements in Outters, of which the following is a specification.

This invention relates to cutters, more particularly to a cutter of the combined chamfering and crozing type, and has for its object to provide, in a manner as hereinafter set forth, a cutter of the class referred to with means for simultaneously chamfering and crozing one end of a dry or green barrel stave without tearing or splitting'the stave.

Further objects of the invention are to provide, in a manner as hereinafter set =lforth, a cutter of the type'referred to, which is simple in its construction and arrangement, strong, durable, compact, readily assembled, thoroughly efiicient in its use, and comparatively inexpensive to manufacture.

fWith the foregoing and other objects in view, the invention consists of the novel construction, combination and arrangement of parts, ashereinafter more specifically described and illustrated in the accompanying drawings, wherein is shown .an embodiment of the invention, but it is to be understood that changes, variations and modifications can be resorted to which come within the scope of the claims hereunto appended.

in In the drawings wherein like reference characters denote corresponding parts throughout the several views Figure 1 is aside elevation of a cutter in accordance with this invention. Figure 2 is a section on line 22, Figure 1 I Figure 3 is a section on line 3-3, Figure 2.

Figure 4: is a section on line 4- 1, Figure 2.

Figure 5 isa top plan view of the chamfering bit holder.

Figure 6 is a top plan view of the crozing bit holder. Figure 7 is a perspective view of a chain fering bit.

Figure 8 is a perspective view of a crozing, bit. I

Referring to the drawings in detail, the as head t the putter'i relules a pair at l'etain- Serial No. 751,084..

ing disks 1, 2, and a pair of bit holders 3, 4. The disks and holders are circular in contour, of like diameter and are provided with registering openings 5 for the passage of an operating shaft 6, to which the head is fixedly secured, whereby the head will be revolved with the shaft 6. The disks and holders can be secured to the shaft 6 in any suitable manner, by way of example the disks and-holders are keyed to the shaft 6, as indicated at 7. The disk 1 abuts against the collar 8 carried by the shaft 6, and the latter projects outwardly from the disk :2 and is formed with a reduced outer end 9'. Threadedly engaging with the projecting end of the shaft 6 is a clamping nut 10, which abuts against the disk 2. Any other suitable method or means can be employed for securing the head to the shaft 6.

The inner face of each of said disks is plane and the outer face 7 thereof tapers from the edge of the opening 5 to the outer edge 8 of the disk whereby the thickness of the diskwill gradually decrease outwardly. The disk 1 is positioned against the outer side of the holder 3, and the disk 2 against the outer side of the holder 4.

The holder 3 is adapted to have connected therewith a series of chamfering bits and the construction of the bits will be presently referred to. The holder 4: is adapted to have connected therewith a series of crozing bits, and the construction of these bits will be presently referred to.

The holder 3 is of materially greater thickness than the holder 4 and is formed with a series of spaced diagonally extending grooves 9 and each of the latter has one side wall thereof, at its inner end, offset as at 10, whereby the grooves will be angleshaped in contour. The grooves 9 open at the sides and at the edge of the holder Preferably the holder 3 is formed with twenty grooves, but the number thereof can be increased or diminished if desired.

The bit holder 4: has its mner face positioned against the inner face of the holder of the grooves 11 is less than the length of the grooves 9, in View of the fact that the holder 4 is of less thickness than the holder 3.

When the holders 3 and 4 are in abutting engagement, the inner end of the grooves 10 register with the inner end of the grooves 11.

The grooves 9, in the holder 3 are provided for connecting thereto a series of stave chamfering bits 13 and each of which consists of a rectangular body portion 14 pro vided with a lengthwise extending rib 15 on the inner portion of the follower side thereof, and which when the bit is mounted in position extends into the offset portion 10 of the groove 9. The end 16 of the body portion 14 is of greater height than the end 17 of said body portion, and the leading side 18 of said body portion 14 is of greater height than the follower side 19. The leading side 18 of the body portion 14, at the top thereof, gradually decreases in height from the end 18 to the end 17 of the body portion 14, as indicated at 20. The outer longitudinal edge of the body portion 14 is bevelled in an upward direction form the follower side 19 to the leading side 18, as indicated at 21. The length of the body portion 14 is the same as the length of a groove 9, and when the bit is mounted in the holder 3 the ends 16 and 17 thereof are flush with the sides of said holder. The bits are dis posed diagonally when mounted in the hold er 3 and project a substantial distance from the grooved edge of the holder and provide in connection with the holder what may be termed a saw. The ribs 15, in connection with the offset portions 10 of the grooves 9 provide means for retaining the chamfering bits in the holder during the operation of the cutter.

The grooves 11 in the holder 4 provide means for the mounting in the holder of the crozing or other type of bits. Each of the crozing bits consists of a rectangular body portion 22 having a tapered projection 23 at the outer end thereof and further pro vided on one side at the inner end thereof, with a rib 24 which seats in the offset portion 12 of the groove 11 and provides means for retaining the bit in the holder during the operation of the cutter. The body portion 22 is flush with the sides of the holder 4, and the projection 23 extends a substantial distance from the edge of the holder 4, and when the series of'crozing bits is mounted in the holder 4, the projections 23 provide a saw.

Vhen the bits are mounted in the holders 3 and 4, and the holders positioned in abutting engagement, the chamfering bits carried by the holder 3 abut against the crozing bits carried by the holder 4.

The grooves 9 and 11, in connection with the disks 1 and 2 provide sockets for detachably securing the bits in cutting position.

When the chamfering bits and crozing bits are mounted in position and the cutter operated, the inner face of the stave will be chamfered and provided with a croze simultaneously. When the charnfering bits are mounted in position and the cutter operated, the inner face of the staves will be chamfered.

It is thought that the many advantages of a cutter'in accordance with this invention, can be readily understood, and although the preferred embodiment of the device is as illustrated and described, yet changes in the details of construction can be had which will fall within the scope of the invention as claimed.

What I claim is 1. In a cutter for the'purpose set forth, a pair of abutting bit holders each provided with a series of bit receiving grooves opening at the edge and sides thereof, each of said grooves having one side wall thereof offset at its inner end, the grooves in one of said holders disposed diagonally throughout with respect to the edge thereof and the grooves in the other of said holders extending throughout parallel to the axis thereof, the diagonally extending grooves being of a greater length than and registering at their inner ends with the inner ends of the other of said grooves, said holders being circular and of like diameter, and a bit retaining disk positioned against the outer face of each of and of the same diameter as said holders. r I 1 2a,

2. In a cutter for the purpose set forth, a pair of abutting bit holders each provided with a series of bit receiving grooves opening at the edge and sides thereof, each of said grooves having one side wall thereof offset at its inner end, the grooves in one of said holders disposed diagonally throughout with respect to the edge thereof and the grooves in the other of said holders extending throughout parallel to the axis thereof, the diagonally extending grooves being of greater length than and registering at their inner ends with the inner ends of the other of said grooves, said holders being circular and of like diameter, and a bit retaining disk positioned against the outer face of each of and of the same diameter as said holders, that holder provided with the diagonal grooves being of greater thickness than the other holder.

3. In a cutter for the purpose set forth a pair of abutting bit holders each provided with bit receiving grooves opening at the edge and sides thereof, each of said grooves having the inner end of one side wall there or offset, the grooves in one of said holders extending at an angle throughout with respect .to' the .grooves in the other of said holders, the inner ends of the grooves in one of said holders registering With the inner ends of the grooves in the other of said holders, that holder provided with the angularly disposed grooves of greater thickness than the other of said holders, said holders be ing circular and of like diameter, and a circular bit retaining disk positioned against the outer face of each of said holders and overlap ing the outer ends of the grooves 10 in that older against which the disk is positioned,

In testimony whereof, I aflix my signature hereto.
